Apple Battery Replacement UPSELL
I sent an iPhone 6 with a minor scratch on the glass in for battery replacement (and prepaid the cost of replacement and handling) this spring.
They refused to replace the battery unless they also replaced the entire screen. This would have added an extra $100 to the cost and was not necessary...
After several weeks of communications including phone calls to the service center I had them send the phone back without any work done. They never refunded any of the replacement cost. This was extremely inconvenient and a waste of my time & money - fortunately for me this was only a backup phone.
